When converting or upgrading a van into a comfortable living space, few upgrades matter as much as campervan roof insulation. Whether you’re exploring Australia’s hot coastlines or cool mountain regions, proper insulation keeps your van comfortable year-round — cooler in summer, warmer in winter, and quieter on the road.
In this guide, we’ll explain the best materials for insulation, how to install them, and the key benefits of adding insulation for caravans and vans.
Why Campervan Roof Insulation Matters
The roof of your campervan is constantly exposed to the sun’s radiant heat. Without insulation, that heat easily transfers inside, creating an uncomfortable, stuffy environment. Likewise, in colder weather, warm air escapes quickly through an uninsulated roof.
Adding quality campervan roof insulation helps:
- Maintain comfortable interior temperatures
- Prevent condensation and mould
- Reduce outside noise
- Improve energy efficiency when heating or cooling
Kool Wrap offers a full range of van insulation and heat protection products designed specifically for Australian touring conditions.
Best Materials for Campervan and Caravan Insulation
Choosing the right material is essential for effective insulation for caravans and vans. Here are the most popular and efficient options:
1. Aluminium-Foil Foam Insulation
Lightweight and reflective, this material blocks radiant heat while also reducing sound. Kool Wrap’s Adhesive Van Liner Heat & Sound Shield combines foil and foam layers to create a thermal and acoustic barrier — perfect for roofs, walls, and doors.
2. Multi-Layer Reflective Insulation
For those seeking extra performance, Kool Wrap’s Underfloor and Roof Aluminium Fibreglass Insulation features six layers of embossed aluminium and fibreglass that reflect up to 95% of radiant heat.
3. Van Sound Deadening Insulation
If you’re converting your camper into a travel home, van sound deadening insulation is equally important. It reduces road vibration and exterior noise while helping to stabilise cabin temperature. Explore Kool Wrap’s Sound Deadener & Van Liner Kit — designed for standard wheelbase vans and ideal for roof and wall coverage.
How to Install Campervan Roof Insulation
Installing insulation is straightforward, even for DIY enthusiasts. Follow these simple steps for a professional finish:
1. Clean and Prepare the Roof Surface
Remove dust, grease, and debris to ensure the adhesive bonds properly.
2. Measure and Cut the Insulation
Kool Wrap’s insulation sheets are easy to trim with scissors or a utility knife. Cut sections to fit roof panels precisely.
3. Peel and Stick
Most products, such as our Adhesive Van Liner, feature a strong heat-resistant adhesive. Peel off the backing and apply firmly.
4. Seal Gaps and Joints
Use heat-resistant aluminium tape to cover seams and ensure an airtight barrier.
5. Add a Finishing Layer (Optional)
For maximum sound and temperature control, you can combine multiple layers — a base sound deadener topped with foil-backed insulation.
Key Benefits of Campervan Roof Insulation
1. Improved Comfort in Any Climate
A well-insulated roof keeps the van cooler in hot Australian summers and warmer during cold nights — reducing reliance on air conditioning or heating.
2. Noise Reduction
Using van sound deadening insulation helps eliminate road, wind, and rain noise, making travel and sleep quieter and more comfortable.
3. Moisture and Condensation Control
Insulation reduces condensation buildup on metal surfaces — a common cause of rust and mould in caravans and vans.
4. Energy Efficiency
Efficient insulation keeps temperatures stable longer, meaning less energy is needed to maintain comfort — perfect for off-grid or battery-powered setups.
